This pull request implements MSC4406: M_SENDER_IGNORED error code.

Pull request checklist:

  • This pull request targets the main branch, and the branch is named something other than
    main.
  • I have written an appropriate pull request title and my description is clear.
  • I understand I am responsible for the contents of this pull request.
  • I have followed the contributing guidelines:
<!-- In order to help reviewers know what your pull request does at a glance, you should ensure that 1. Your PR title is a short, single sentence describing what you changed 2. You have described in more detail what you have changed, why you have changed it, what the intended effect is, and why you think this will be beneficial to the project. If you have made any potentially strange/questionable design choices, but didn't feel they'd benefit from code comments, please don't mention them here - after opening your pull request, go to "files changed", and click on the "+" symbol in the line number gutter, and attach comments to the lines that you think would benefit from some clarification. --> This pull request implements [MSC4406: `M_SENDER_IGNORED` error code](https://github.com/matrix-org/matrix-spec-proposals/pull/4406). <!-- Example: This pull request allows us to warp through time and space ten times faster than before by double-inverting the warp drive with hyperheated jump fluid, both making the drive faster and more efficient. This resolves the common issue where we have to wait more than 10 milliseconds to engage, use, and disengage the warp drive when travelling between galaxies. --> <!-- Closes: #... --> <!-- Fixes: #... --> <!-- Uncomment the above line(s) if your pull request fixes an issue or closes another pull request by superseding it. Replace `#...` with the issue/pr number, such as `#123`. --> **Pull request checklist:** <!-- You need to complete these before your PR can be considered. If you aren't sure about some, feel free to ask for clarification in #dev:continuwuity.org. --> - [x] This pull request targets the `main` branch, and the branch is named something other than `main`. - [x] I have written an appropriate pull request title and my description is clear. - [x] I understand I am responsible for the contents of this pull request. - I have followed the [contributing guidelines][c1]: - [x] My contribution follows the [code style][c2], if applicable. - [x] I ran [pre-commit checks][c1pc] before opening/drafting this pull request. - [x] I have [tested my contribution][c1t] (or proof-read it for documentation-only changes) myself, if applicable. This includes ensuring code compiles. - [x] My commit messages follow the [commit message format][c1cm] and are descriptive. - [x] I have written a [news fragment][n1] for this PR, if applicable<!--(can be done after hitting open!)-->. <!-- Notes on these requirements: - While not required, we encourage you to sign your commits with GPG or SSH to attest the authenticity of your changes. - While we allow LLM-assisted contributions, we do not appreciate contributions that are low quality, which is typical of machine-generated contributions that have not had a lot of love and care from a human. Please do not open a PR if all you have done is asked ChatGPT to tidy up the codebase with a +-100,000 diff. - In the case of code style violations, reviewers may leave review comments/change requests indicating what the ideal change would look like. For example, a reviewer may suggest you lower a log level, or use `match` instead of `if/else` etc. - In the case of code style violations, pre-commit check failures, minor things like typos/spelling errors, and in some cases commit format violations, reviewers may modify your branch directly, typically by making changes and adding a commit. Particularly in the latter case, a reviewer may rebase your commits to squash "spammy" ones (like "fix", "fix", "actually fix"), and reword commit messages that don't satisfy the format. - Pull requests MUST pass the `Checks` CI workflows to be capable of being merged. This can only be bypassed in exceptional circumstances. If your CI flakes, let us know in matrix:r/dev:continuwuity.org. - Pull requests have to be based on the latest `main` commit before being merged. If the main branch changes while you're making your changes, you should make sure you rebase on main before opening a PR. Your branch will be rebased on main before it is merged if it has fallen behind. - We typically only do fast-forward merges, so your entire commit log will be included. Once in main, it's difficult to get out cleanly, so put on your best dress, smile for the cameras! --> [c1]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md [c2]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/docs/development/code_style.mdx [c1pc]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#pre-commit-checks [c1t]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#running-tests-locally [c1cm]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#commit-messages [n1]: https://towncrier.readthedocs.io/en/stable/tutorial.html#creating-news-fragments

wording clarification suggestion:

Determine whether a PDU should be "ignored" for a given recipient user.

- Returns Ok(false) if the PDU should be sent to the user's clients as normal.
- Returns Ok(true) if the PDU should be _silently_ hidden from the user's clients.
- Returns Err if the client should be served an error indicating that the PDU they requested was ignored by the user.

alternatively, refactor this to return an enum to make it a bit clearer what's going on
